LOG-TRANSFER.

Specification of Letters Patent.

Patented Jan. 1, 1907.

To all whom it may concern:

Be it known that I, SEYMOUR L. VANCE, a citizen of the United States,residing at Kinzua, in the county of Warren and State of Pennsylvania,have invented certain new and useful Im rovements in Log-Transfers, ofwhich the fo lowing is a specification.

This invention relates to new and useful improvements in transferringdevices, and it especially has reference to log-transfers.

The present invention aims to provide a sectional runway and a car orboat slidable therein. It is especially designed to provide a runway inwhich the sections may be disassembled from one another and are'independently ortable in order that they may e moved om lace to placein the logging country, where y the sections beng independently portablethe runway constructed thereof may be set up as an entirety in differentplaces.

The detailed construction will appear in the course of the followingdescription, in which reference is had to the accompanying drawings,forming a part of this specification, like numerals designating likeparts throughout the several views, wherein Figure 1 is a perspectiveView of the logtransfer constructed in accordance with the presentinvention. Fig. 2 is a vertical transverse section thereof. Fig. 3 is aside elevation, and Fig. 4 is a detailed perspective of sections of therunway.

In the practical embodiment of my invention I employ a runway 1,arranged in an inclined plane, and a car or boat 2, slidable therein.The runway 1 is composed of counterpart sections 3, formed with inclinedtop surfaces 4. The sections 3 are arranged in parallel confrontingrelation, so as to afford a runway for the car or boat 2 of substantialV shape and between the inclined sides of which said car or boat hasmovement. The sections in their assembled relation, as above described,are supported in recesses 5, provided in transverse skids 6, which arearranged centrally of the length of the sections and adjacent to themeeting edges thereof. The

sections 1 are severally formed in their inclined sides 4 at regularintervals with recesses 7, which are arranged in alinement in pairs inthe parallel relation of the said inclined sides. Transversely journaled in said recesses in any approved manner are rollers 8, uponwhichthe boat 2 is su ported, and said rollers serve to take up ictionin the movement of the boat along said runway. The boat 2 is constructedwith a body 9 of substantially the same cross-sectional shape as saidrunway. The body 9 is formed with a flat bottom 10, which rides upon therollers 8. End pieces 11 are provided in the body 9, and said end piecescarry corner-standards 12.

In practical use it is designed that the car or boat 2 shall be ofsufficient capacity to carry approximately a cord of wood. The woodhaving been placed upon said car or boat 2 between the standards 12, asshown in Fig. 3, said car gravitates down the inclined runway 1 to thedesired destination. The car or boat 2 travels upon the rollers 8 withits flat bottom 10, and the inclined sides of said car extend parallelto and are closely associated with the inclined sides of the runway 1.The sections 3 are secured to the skids 6 by bolts or other approvedfastening means. Said sections may severally be re moved from said skidsand are of a size to be carried about from place to place by a laborer,whereby the runway may be disassembled in one place and progressivelyconstructed in another place.

It is obvious that various minor changes may be made in the inventionwithout departing from the spirit and scope thereof as defined in theappended claim.

Having fully described my invention, I claim A log-transfer embodying aninclined runway formed with counterpart sections severally provided withinclined upper surfaces which mutually converge in the parallel relationof said sections, rollers journaled transversely of-said runway andbetween said sections, and a car or boat slidable in said runway andformed with a flat bottom designed to ride upon said rollers and withinclined sides overlying for a short distance the inclined sides of saidsections.

In testimony whereof I afliX my signature in presence of two witnesses.

SEYMOUR L. VANCE.
